英文摘要: Regions and localities may lose many species to extinction under rapid climate change andmay gain other species that colonize from nearbywarmer environments. Here, it is argued that warming-induced species losses will generally exceed gains and there will be more net declines than net increases in plant community richness. Declines in richness are especially likely in water-limited climates where intensifying aridity will increasingly exceed plant tolerances, but also in colder temperature-limited climates where steep climatic gradients are lacking, and therefore, large pools of appropriate species are not immediately adjacent. The selectivity of warming-induced losses may lead to declines in functional and phylogenetic diversity as well as in species richness, especially in water-limited climates. Our current understanding of climatecaused diversity trends may be overly influenced by numerous studies coming from north-temperate alpinemountaintops,where conditions are unusually favourable for increases-possibly temporary-in local species richness. © 2019 The Author(s) Published by the Royal Society.
